Use of envelopes:
Grammage of the envelope is expressed in grams per square meter. The higher the grammage, the more durable the envelope.
We also offer postal envelopes with different types of flaps that can used according to the purpose of the envelope.

Most frequently used envelopes:
• with a straight flap (classical postal envelope and envelopes for mechanical folding).

The durability of the envelope is also dependent on the type of paper from which it is made.
Envelopes for automatic folding of documents. Flaps of such envelopes may have a rounded or trapezoidal shape.
